FZN61-12Indoor high-voltage vacuum load switch|Hongtuo Transformer Co., Ltd

summary:

FZN61-12 indoor high-voltage vacuum load switch is an indoor high-voltage vacuum isolating load switch (circuit breaker) with AC 50Hz and rated voltage of 12kv developed by our company using its own technology. Its appearance design is special and novel, the distribution equipment has simple structure, good practical performance, and smaller cabinet width and volume, which can be used for looped network power supply equipment in industrial and mining enterprises, residential quarters, schools and other distribution systems.

Switch structure features:

FZN61-12 indoor high-voltage vacuum load switch is a modular design product, which integrates vacuum switch, isolating switch, grounding switch, fuse holder, and operating panel switch elements, and can select electric operation and auxiliary contact.

The rotary disconnector has obvious fracture after opening. The disconnector and the grounding switch belong to linkage operation. At the same time, the mechanical interlock between the disconnector and the vacuum switch and the cabinet door also meets the "five prevention" interlocking requirements of the complete set of high-voltage equipment. In particular, the interlocking function of "interlock" is also added in the operation hole of the panel, so that the front and rear of the whole switch have a dual "five prevention" interlocking function.

The switch volume is small, the width of the vacuum load switch is ≤ 299mm under the opening and closing state, and the rated current of the vacuum load switch (circuit breaker) is up to 1250A. The rated current of the combined appliance is up to 200A, which can protect the transformer of 200KVA.
